This may be a silly topic, but I was curious...with Terminal 2 closing the doors for good next week, there will now only be Terminal 1 and Terminal 3 which makes me wonder, would they rename T3 to Terminal 2??? It would only make sense would it not? Or would it only cause confusion with travellers???

The general consensus has been to not renumber terminals when one is consolidated out of existance, though that is not a steadfast rule. For example, there is no Terminal 1 at PHX in honor of that airport's first terminal that was torn down some years ago. Similarly, BOS recently stopped calling the stub gates between C and E Terminal D and include them with the connected Terminal C now. They have not, however, renamed international terminal E.

Doesn't really make sense to me.....in the short term there could be some confusion, renaming the existing T3 to T2, but in the long term it makes a lot of sense to rename if there are going to be only 2 terminals.....

I think in the very long term T3 is either going to be torn down or eventually linked into the new T1 superterminal anyway so way down the road there may not be any need for numbered terminals but rather perhaps lettered piers etc.

However the plan is for them to rename terminal E to terminal D sometime later this year.

Excerpt:"The ultimate terminal development plan, illustrated in Figure 12, calls for a unified, single terminal building with 6 piers radiating from a common horseshoe-shaped central processing facility. The ultimate concept, which would be developed once Terminal 3 has reached the end of its operational
life, will have 135 bridged gates, and the capability to process up to 55 million passengers annually, matching the ultimate capacity of the six
runway system."
